No ZJ here, but my cousin just acquired a '96 ZJ with the 5.2L and the Full-Time 4WD TC (not sure the number designation...4FT-N-4LO). Anyway, when the Jeep is backing up and turning, something in the front-end will make a single pop sound. The side of the pop matches the side turning (wheels turned right, right side pop). This happens in either direction. It does not, however, occur when going forward. Anyone have a clue?_________________1998 Jeep Cherokee Sport: 4.0L, AW4, 235/75 Wild Spirit's
